Editors' Review

This simple application lets you easily change the extension of a single file or multiple files within a folder, though it offers little else in the way of features or capabilities. Extension Changer offers two ways to change file extensions. Open the program and drag and drop files or folders into a small inset box under the Main tab, fill in the new extension, and press Change. The easier method is to right-click on files and folders and select Edit the extension. Your document or folder is already displayed and you need only type the new extension. Changes were immediately applied. Desktop and Start menu shortcuts aren't automatically added, but since the program is so easily available when it's needed, this isn't a problem. A simple tool is offered to search for more information on extensions. This utility is easy to use, does exactly what it says, and is offered free of charge.

It does indeed change the file extension visually, however other programs do not recognize the extension as a valid format. (ex.) I wanted to change several .png files to .gif, in order to make an animated .gif file. I tried 4 different programs, neither recognized the file as a .gif.

This review is very strange indeed. What you want is something that converts FORMATS (e.g. from one image format to another). This program does not do that, and does not claim to do that. It assumes that people want to change file EXTENSIONS, that they have reasons for doing so, and that they know what they're doing. If this is what you need, the program delivers.

simple and intuitivejust mark a block of files and drag them to the program windowfile endings can be entered as wished (i.e. jpg.bmp)

Cons

not well explained - needs some trial and error until you know how to get exactly what you needas mentioned in a review above, if you enter a dot before your ending, your result will have 2 dotsdoes not install link to start menu only to desktop - has to be manually movedcloses after each job

Summary

only changes the extension, but that is exactly what i need. the problems were quickly apparent and easily avoided. after that, the program reliably gave me the results i needed.despite the problems the program has, i give it 5 stars in anticipation of all the work it will save me in the future!Love it.

UPDATE: caution: leaving the extension field blank removes the extension

1. misleading prompts (e.g. looking at .* you might think is wants you to enter .doc for example, where in fact it is just doc)2. Impossible to cancel (other than answering to a yes/no window for every single file . Well , I had 1000 files to rename and had to hit damn button 1000 times ? Try it and you start to hate this small beauty in 2 min)

Summary

Room for improvements. Don'r expect too much from the program. It's not a product yet

Yeah, I'm not sure you have this program or this build, or you're using it the correct way.

The best way to use Extension Changer is to open Windows Explorer, find the files you need to change the extensions of, highlight the files, right click on the highlighted files, and choose "Edit the Extension." In the box you type in the name of the extension you want to change it to. Make sure all of the files you highlighted are the same type, such as changing TXT files to DOC files, or something like that. You click Change and the program will do the rest instantly. There is no ".*" that appears in the Change box. And there are no "Yes/No" windows that pop up. The only problem I've had is when changing over 300+ extensions.

As for the person saying the program won't stay open, if you use it through Windows Explorer, then it's not an issue. You highlight, right click, and type in the new extension name. It closes so you can go on to the next group of files you want to change.

I found this simple to install and use. I needed to change the file extension on multiple pictures, from jpeg to jpg and just by blocking and dragging multiple pictures to the '.exe' program, I had the job done. Previously I changed each picture manually. What a drag.

Cons

None that I found.

Summary

Great program if you need to simplify modifying the extensions on multiple files.

Small on screen when opened and it closes automatically when the job is done. Easy to use- open files- drag the file you want to change extension into the little box- type in the desired format than click 'change'.

Cons

None at the moment.

Summary

Changes file with two extensions i.e- filename.avi.html to one extension filename.avi.PLEASE NOTE- it does not CONVERT formats, it only removes an extension. Provided the existing file already exist in the original file than your media player should not have any problem running it.

sabe_in_el_paso - this program changes extension of the file - not its format. if you wanna play a video and can't, download a free video converter program "any video converter" and convert the video. merely changing the extension of the file will not modify its codec. hope that helps!!!
